Hi Team,
Could someone provide guidance on how to customize API responses in Ataccama MDM (version 15.4.1)?
Our requirement is to conditionally exclude certain child records from the API response based on a relationship-type attribute. For example, a single party may have multiple identifiers such as SSN, TIN, ABC, etc. When a consumer application makes a GET API call, we need logic that checks whether an ABC-type identifier exists. If it does, the API should stop further processing and return the response accordingly (e.g., prioritizing or limiting the payload based on this condition).
How can this kind of conditional filtering or response control be implemented—preferably within Ataccama (configuration, query layer, or business rules), rather than handling it downstream?
Regards,
